Reduce the memory footprint of software rendering (#1973)

As of #1952, Lottie now handles its own bitmaps for software rendering. This was causing an issue for very large compositions. Lottie was creating a bitmap at the size of the entire composition which was often far larger than was needed.

The most common case for this to happen is when people make 1928x1080 compositions in After Effects thinking it's 1:1 with displays. However, Lottie treats dimensions in dp which would cause a 1080p composition to have ~6000x4000 pixel bounds.

With this PR, Lottie will now calculate the largest area that the bitmap can be rendered in given either its bounds, scale, or scaleType and then render a smaller bitmap to a larger area in the original canvas.
